Question

the side of triangle is 6m 9 m 13 m find which of them is right angled triangle ​

Answer 1

Answer:

No..

Step-by-step explanation:

(13)^2 = 169

(6)^2 + (9)^2 = 36+81 = 117

Therefore, it is not a rights angle triangle..

Answer 2

Answer:

If the side of the triangle is 6m 9 m 13 m then the triangle is right-angled triangle ​.

Step-by-step explanation:

A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle .

A Pythagorean triple consists of three positive integers a, b, and c, such that $a^2 + b^2 = c^2$.

a = 6m b = 9 , and c= 13 m

$c^2 = 13^2 = 169\\a^2 + b^2 = 6^2 + 9^2 = 36 + 81 = 117\\c^2\neq a^2 + b^2$

So, the given triangle is not right-angle triangle.
